I have several reports that are from SSAS 2008, but one of them has to drill through to a SQL Server report simply because the data is far to granular for a cube.
Any tips on passing parameters? Of course they are passed in as MDX, and I can't figure out a way to get just the "Key" with the source MDX. Surprisingly I can't find a lot of pointers on this.
Let me know if this is too vague...
Are you getting the MDX passed in as a string which you can examine and fiddle with? If you can extract the dimension and member name, you could look up the name in the SQL database to find the ID required, which could then be passed on?
I assume you are getting strings like this:
[Location].[All location].[South].[Surrey].[Guildford]
If you look up 'Guildford' in your SQL db you'll be able to find out it is row 2134 and that's what you need?
I'm assuming that you want to call this report from a report action. If your attribute has a single column key you can reference it using something like:
[<dimension>].[<hierarchy>].CurrentMember.Properties("MEMBER_KEY")
If your attribute has multiple key columns you would use KEY0, KEY1, etc to reference the individual parts instead of MEMBER_KEY

i have some problems displaying my aws timestream data in grafana. I added as a global dashboard variable DevEUI with 3 different specific values. But when i am using the multivalue syntax ${DevEUI} in my query with more then one value i get everytime a error.
hope somebody can give me a hint.
Regards and thanks in advance
You are most probably having a list of values as the value of your multivalue Grafana variable, but you are still using the = operator in your query. Try ... and DevEUI IN ('${DevEUI}'). Or maybe without the single quotes or the parantheses... the exact syntax depends on your Grafana variable.
But, this is just an educated guess, since I cannot see neither your database schema nor the definition of this Grafana variable (both of which are important details in a question like yours, for future reference).
This is how I did it for a multivalued string value:
timestream_variable_name = ANY(VALUES ${grafana_variable_name:singlequote})
You might have to adjust the formatting Grafana applies to the concatenated variable value it generates, depending on your data type.
I know this is long after the original question but #alparius pointed me in the right direction so I wanted to update the fix for the problem Joe reported.
Use formatting to get the proper quotes/values when formatting your query. Something like this:
Select * from database where searchiterm IN (${Multi-Value_Variable:sqlstring})
I have to extract data in Power BI using a SQL statement. It is a simple select ... from ... group by ... and then I retrieve for example the value 925. And here is my request. What I want is to retrieve 9,25 directly with the SQL statement but I can't find how. When I use a Cast or Convert I always retrieve 9 without the decimals. And if I use the Data Type "percentage" from the Query Editor it will display 925000 so this is not the solution.
Any idea ?
For a simple query pattern like that, I would not bother with a custom SQL statement. Just connect to the source table/view using the Navigation UI, then add a Group By step in the Query Editor window.
You will have less code to maintain (actually none), and the underlying datatypes will be passed through automatically.
I have a table that contains, among other things, about 30 columns of boolean flags that denote particular attributes. I'd like to return them, sorted by frequency, as a recordset along with their column names, like so:
Attribute Count
attrib9 43
attrib13 27
attrib19 21
etc.
My efforts thus far can achieve something similar, but I can only get the attributes in columns using conditional SUMs, like this:
SELECT SUM(IIF(a.attribIndex=-1,1,0)), SUM(IIF(a.attribWorkflow =-1,1,0))...
Plus, the query is already getting a bit unwieldy with all 30 SUM/IIFs and won't handle any changes in the number of attributes without manual intervention.
The first six characters of the attribute columns are the same (attrib) and unique in the table, is it possible to use wildcards in column names to pick up all the applicable columns?
Also, can I pivot the results to give me a sorted two-column recordset?
I'm using Access 2003 and the query will eventually be via ADODB from Excel.
This depends on whether or not you have the attribute names anywhere in data. If you do, then birdlips' answer will do the trick. However, if the names are only column names, you've got a bit more work to do--and I'm afriad you can't do it with simple SQL.
No, you can't use wildcards to column names in SQL. You'll need procedural code to do this (i.e., a VB Module in Access--you could do it within a Stored Procedure if you were on SQL Server). Use this code build the SQL code.
It won't be pretty. I think you'll need to do it one attribute at a time: select a string whose value is that attribute name and the count-where-True, then either A) run that and store the result in a new row in a scratch table, or B) append all those selects together with "Union" between them before running the batch.
My Access VB is more than a bit rusty, so I don't trust myself to give you anything like executable code....
Just a simple count and group by should do it
Select attribute_name
, count(*)
from attribute_table
group by attribute_name
To answer your comment use Analytic Functions for that:
Select attribute_table.*
, count(*) over(partition by attribute_name) cnt
from attribute_table
In Access, Cross Tab queries (the traditional tool for transposing datasets) need at least 3 numeric/date fields to work. However since the output is to Excel, have you considered just outputting the data to a hidden sheet then using a pivot table?
I have a table called book with, the attrbutes are booked_id, yearmon, and day_01....day_31. Now i need to unpivot the table and transform day_01...day_31 into rows, I have successed in doing that, but the problem is that my yearmon is a format of 200805 and i need to append a day to it based on day_01 or day_02 etc, so that i can create a new column with date information for example, if it is day_01, it looks like 20080501. Instead of writing huge query, does anyone how to use ssis to tranform it
You should be able to use the Unpivot component and the Derived Column component to do what you need. Look into those and post back if they don't seem to do what you need.
I have 150+ SQL queries in separate text files that I need to analyze (just the actual SQL code, not the data results) in order to identify all column names and table names used. Preferably with the number of times each column and table makes an appearance. Writing a brand new SQL parsing program is trickier than is seems, with nested SELECT statements and the like.
There has to be a program, or code out there that does this (or something close to this), but I have not found it.
I actually ended up using a tool called
SQL Pretty Printer. You can purchase a desktop version, but I just used the free online application. Just copy the query into the text box, set the Output to "List DB Object" and click the Format SQL button.
It work great using around 150 different (and complex) SQL queries.
How about using the Execution Plan report in MS SQLServer? You can save this to an xml file which can then be parsed.
You may want to looking to something like this:
JSqlParser
which uses JavaCC to parse and return the query string as an object graph. I've never used it, so I can't vouch for its quality.
If you're application needs to do it, and has access to a database that has the tables etc, you could run something like:
SELECT TOP 0 * FROM MY_TABLE
Using ADO.NET. This would give you a DataTable instance for which you could query the columns and their attributes.
Please go with antlr... Write a grammar n follow the steps..which is given in antlr site..eventually you will get AST(abstract syntax tree). For the given query... we can traverse through this and bring all table ,column which is present in the query..
In DB2 you can append your query with something such as the following, but 1 is the minimum you can specify; it will throw an error if you try to specify 0:
FETCH FIRST 1 ROW ONLY
